Abstract (en)
[origin: CN113321421A] The invention relates to crystallizable lithium aluminosilicate glass used for manufacturing transparent glass ceramic. The crystallizable lithium aluminosilicate glass comprises following components, based on oxides: 3-5 wt% of Li2O, 19-24 wt% of Al2O3, 62-70 wt% of SiO2, 1.6 wt% (not inclusive) to 2.8 wt% of TiO2, 1-2.5 wt% of ZrO2, 0.01 wt% o 0.5 (not inclusive) wt% of MgO and 0.01 wt% to 0.15wt% (not inclusive) of SnO2, with the condition of 0.005<MgO*SnO2<0.06 (based on wt%; the condition B1a). The invention further relates to the glass ceramic produced by using the glass and use thereof.
